MGB-Tech has a range of products aimed at the calculation, visualization and distribution of wave parameters. All solutions can separate the wave spectrum and calculate the parameters on the sea and swell part. We support the Datawell Waverider buoys in our product range. Depending on your needs, there are multiple telemetry options available.


TARI Controller

We have a modular highly integrated controller that gives you the power to interface up to two Datawell waveriders per module. This module is part of our TARI product range intended to be installed in harsh power restricted environments. The controller starts from the wave spectrum and splits it into a SEASTATE and SWELL component. Then various parameters are calculated on this spectrum. Our ecosystem then provides multiple telemetry and data storage options to get the data to where you want.

  • UHF, GPRS and IRIDIUM telemetry
  • Two waverider inputs
  • Low power consumption
  • 4GB logging SD-CARD
  • Many parameters can be calculated
    • Dpeak : Peak wave direction
    • Dmean : Mean wave direction
    • Tz : zero-up crossing period
    • Hs : Significant wave height
    • Hs_swell : Swell Significant wave height
    • Dpeak_swell : Swell Peak wave direction
    • Dmean_swell : Swell Mean wave direction
    • Tswell : Wave period of the swell
    • Hs_sea : Significant wave height of the seastate
    • Dpeak_sea : Peak wave direction of the seastate
    • Dmean_sea : Mean wave direction of the seastate
    • Tsea : Wave period of the seastate


Tendo is our software solution that handles the data visualization part of our ecosystem. Aside from the real-time data, it handles predictions to combine in your graphs and other visualisations. You can perform automatic Quality Control on your measurements and  send mails when you an alarm is triggered. Tendo can handle a virtually unlimited number of waverider buoys. These can be connected directly to the Tendo computer or via an serial to ethernet converter (e.g. MOXA solution).

  • Merges the different telemetry paths
  • Has TREX dataexchange integrated
  • Multi monitor visualizations
  • Processes and stores the data
  • Runs an integrated webfront

You can run Tendo in the cloud, or on premise.

We have prepared two Tendo station offerings to cover your on premise/on ship needs



Our wave measurement solutions have multiple telemetry options that can be used simultaneously to provide redundancy in your telemetry. Our Tendo based products can handle the reception of data from multiple telemetry paths and merge them gracefully. This is done in such a way that the end-user has the data he needs when he needs it in a transparent manner. This ecosystem feature reduces the risk of relying on a single telemetry path.


A private UHF channel has many advantages and deserves a spot in your telemetry solution. You dont have to rely on an ISP or other service providers to keep your systems running. UHF radio’s have a few draw backs that our ecosystem tackles with implementing TIME SLOTTED UHF. First off all, the UHF channel is in most situations a random access system. When two devices try to send something at the same time, they interfere each other and no data gets trought at all. In many implementations this data is just lost permanently. Another drawback of the UHF system is its limited throughput. The products of our ecosystem give you the option to declare time slots and asign these time slots to devices. Thanks to this feature only one device is transmitting at a time and optimal usage of the available bandwith is achieved.
